You adored her as Col. Sam Carter for 13 years on Stargate SG-1 and Stargate Atlantis, but now Amanda Tapping is launching herself into a new show called Sanctuary (Fridays, 9/8c on Sci Fi). The intriguing show features Amanda as the enigmatic Dr. Helen Magnus who recruits the young and handsome Dr. Will Zimmerman (Robin Dunne) to work with her in her home – which she calls a "Sanctuary for All." She houses and treats all forms of "abnormals" who most people would deem as monsters that should be destroyed. Erin Fox sat down with the First Lady of sci fi to discuss Magnus' background and the challenges of shooting a show almost solely against green screens.
